Introduction

The Banded Wobbegong is a distinctively coloured bottom-dwelling species that occurs on inshore reefs and near offshore islands.

Identification

The Banded Wobbegong can be recognised by its body shape and colouration. It has a broad, flattened head with skin flaps around the snout margin. The eyes are small and oval. The species has two dorsal fins which are positioned posteriorly on the body. The caudal fin has a long upper lobe. The anal fin is positioned so far posteriorly, it almost looks like a lower caudal fin lobe.

The species is usually golden-brown with broad dark areas, and blueish-grey spots above. It is yellowish green below. The margins of the fins often have dark spots.

The similar-looking Spotted Wobbegong occurs in temperate Australian coastal waters from southern Queensland to south-western Western Australia. It can be distinguished from the Banded Wobbegong by its colour pattern which consists of broad dark saddles and distinct circles formed by groupings of small white dots.

The Banded Carpet Shark, Orectolobus halei, looks similar to the Banded Wobbegong. Underwater, they can be difficult to tell apart. Both have saddles, spots and blotches edged in black. Orectolobus halei is a larger fish (growing to at least 2 m in length) which has the pelvic fin insertion at about the level of the first dorsal fin midpoint (versus pelvic fin insertion slightly anterior to the first dorsal midpoint in O. ornatus, which only grows to about 1.1 m in length).

Habitat

The Banded Wobbegong is usually seen in clear water on inshore reefs and offshore islands to depths of at least 50 m. Divers most often see the Banded Wobbegong lying on the bottom during daylight hours.

Distribution

It occurs along the east coast of Australia from the tropics to warm temperate waters.

Life history cycle

According to Last and Stevens, 2009 (see References), "The young are born in September or October after a 10-11 month gestation".

Danger to humans

It is generally not aggressive, however it should be considered as potentially dangerous due to its large size and sharp teeth.
